摘　　要：描述了用常规的有理Ｂｅｚｉｅｒ曲面光滑填充任意Ｎ边域的数学推导和算法细节，并给出该算法的实验结果。所产生的Ｎ边域过渡曲面形式符合ＳＴＥＰ标准。The derivation of the filling of an N-side region with the rational Bezier surface is de-scribed. An Algorithm for automaticalyy generating an Nside region surface of G1 continuitywith the rational Bezier surface and the test results of the algorithm are presented. This al-gorithm can be used for any order of rationaI Bezier surfaces. The N-side region surface con-sists ofNrational Bezier patches and its shape can be interactively adjusted by changing thefullness of the surface, The form of the N-side region surface is in conformity with STEP.
